Median Orbit Repeatability (see table below): 6.0 cm
This week, we add four new candidate global stations. As with other sites,
these sites are given the opportunity to participate in the orbit and clock
solution as the global site distribution varies. The following nominal
coordinates were assumed:
X (m) Y (m) Z (m)
FREE (Freeport, The Bahamas) 1088671.2700 -5596851.5412 2848798.3908
MBAR (Mbarara, Uganda) 5482951.4173 3260442.5106 -66519.9791
PTBB (Braunschweig, Germany) 3844060.1020 709661.2669 5023129.6013
UNB1 (Fredericton, Canada) 1761288.2442 -4078238.6044 4561417.8235
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: Data from PRN17, PRN24 excluded day 196.
WARNING: Data from PRN31 excluded day 200.
WARNING: Data from PRN24 excluded day 201.
WARNING: Data from ANKR, EPRT, HARB, HNPT, LBCH, MEDI, SUWN, WLSN excluded day 196.
WARNING: Data from BRUS, KOUR, LBCH, PETP, RABT, SUWN, WLSN excluded day 197.
WARNING: Data from BRUS, GUAT, HARB, HARV, IISC, IRKT, KWJ1, LBCH, PETP, SPK1, WLSN, WTZT excluded day 198.
WARNING: Data from BRUS, GUAT, HARB, HILO, PETP, SPK1, WLSN, WTZT excluded day 199.
WARNING: Data from HARB, HILO, KELY, SPK1, WTZT excluded day 200.
